Abstract
A method for detecting tracks of touch inputs on touch-sensitive panel, which is applied for an electronic apparatus having a touch-sensitive panel, comprises: during a first period, detecting M touch positions of M touch inputs on the touch-sensitive panel; during a second period, detecting N touch positions of N touch inputs on the touch-sensitive panel, where M and N are positive integers and M is less than or equal to N; selecting a specific touch input from the M touch inputs, where the specific touch input corresponds to a specific touch position of the M touch positions; and determining a track of the specific touch input on the touch-sensitive panel according to N distances that are between the specific touch position and the N touch positions respectively.
